Definitions
- the present invention relates generally to a method, system, and computer program product for troubleshooting an unresponsive microservice. More particularly, the present invention relates to a method, system, and computer program product for improving the availability of API endpoints in container orchestration platforms.
- a microservice architecture is a variant of a service-oriented architecture (SOA) structural style and is one that arranges an application as a collection of loosely coupled services, commonly referred to as microservices due to their narrow scope in executing smaller tasks. It is common for MSA's to be adopted for cloud-native applications, and applications using lightweight container deployment.
- a consequence of following an MSA approach is that the individual microservices are independently deployable and can be individually scaled. In a monolithic approach, an application supporting a plurality of functions would have to be scaled in its entirety even if only one of these functions had a resource constraint. With microservices, only the microservice supporting the function with resource constraints would be scaled out.
- container orchestration platforms have been developed for managing complex applications comprised of multiple microservices working together through application programming interfaces (APIs) that are not dependent on a specific code language. While containers and microservices exist independently and serve different purposes, they are often used together. Containers are an enabling technology for microservices, which is why microservices are often delivered in one or more containers. Since containers are isolated environments, containers can be used to deploy microservices quickly, regardless of code language used to create each microservice. When implementing and managing containers and microservices, DevOps teams must actively work to prevent problematic code, such as errant application code and unresponsive APIs.
- problematic code such as errant application code and unresponsive APIs.
- An embodiment includes a method that invokes, using a service request handler module of a microservice application programming interface (API) fault manager (MAFM) a microservice API fault management service, responsive to detecting an unresponsive microservice managed by a container orchestration platform.
- An embodiment identifies an unresponsive API of the unresponsive microservice using an API inspection module of the MAFM.
- An embodiment determines, using a remedial action module of the MAFM, a remedial action to correct an unresponsive state of the unresponsive API.
- An embodiment communicates, using a container platform interface module of the MAFM, the remedial action to the container orchestration platform.
- An embodiment includes a computer usable program product.
- the computer usable program product includes one or more computer-readable storage devices, and program instructions stored on at least one of the one or more computer-readable storage devices.
- An embodiment includes a computer system.
- the computer system includes one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more computer-readable storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories.

- APIs application programming interfaces
- QA quality assurance
- API testing it generally consists of making requests to a single API endpoint or sometimes multiple API endpoints and validate the response, whether for performance, security, and/or functional correctness.
- container orchestration platforms such as KUBERNETES and DOCKER
- container orchestration platforms when implemented to manage complex application environments having a large number of microservices, generally only provide capabilities to monitor and scale pods (i.e., individual microservices) in the event that there is a failure within a container associated with a plurality of microservices.
- Current container orchestration platform technologies are not designed to validate and take any remedial action(s) based on problems related to the actual application logic and the APIs running within the failing container. As a result, current container orchestration platforms may simply remedy a failing container by replacing it with a newly spawned container, which is identical in the number and organization of microservices and their supporting APIs when compared to the contents of the failed container.
- current container orchestration platforms may mistakenly treat the newly spawned container as a healed container, when in reality one or more of the supporting APIs are unresponsive and the API's failed state remains undetectable to current container orchestration platforms. This causes the application as a whole to become unresponsive.
- the illustrative embodiments also recognize that traditional third-party tools for monolithic applications, which provide fault tolerant and high availability solutions, are ineffective in microservice-based environments because of their inability to perform API validation and healing. Moreover, illustrative embodiments recognize that other solutions for monolithic environments, such as network devices and API gateways providing continuous API monitoring, carry the cost of performance degradation. Even other solutions designed for microservice-based environments fail to perform API validation and healing. Further, illustrative embodiments recognize that current microservice-based implementations employ application logics to perform checks on error codes and perform remedial actions based on the type of error code. However, even if a container orchestration platform terminates a pod and spawns another pod, such actions still do not guarantee individual API validation and healing.
- the illustrative embodiments recognize that the presently available solutions do not address these needs or provide adequate solutions for these needs.
- the illustrative embodiments used to describe the invention generally address and solve the above-described problems and other problems related to improving the availability of API endpoints under the management of container orchestration platforms in a microservice operating environment.
- An embodiment can be implemented as a software application.
- the application implementing an embodiment can be configured as a modification of an existing API gateway, a modification of an existing container orchestrator platform, as a separate application that operates in conjunction with an existing API gateway, as a separate application that operates in conjunction with an existing container orchestrator platform, a standalone application, or some combination thereof.
- some illustrative embodiments provide a method that facilitates improving the availability of API endpoints under the management of container orchestration platforms in a microservice operating environment.
- An embodiment configures a microservice application programming interface fault manager (MAFM) to identify an unresponsive API and to determine a remedial action.
- the MAFM operations are triggered by a fault that is detected and communicated to a service request handler of the MAFM by third party monitoring tools, such as PROMETHEUS and GRAFANA.
- the MAFM operations are triggered by a fault that is detected and communicated to the MAFM by an API gateway that is unable to gain a response from a requested API.
- the fault detected by the API gateway appears to originate at a requested API, but it is not conclusive to be the actual source of the fault, as the requested API may itself depend upon other nested APIs.
- Another embodiment configures an API inspection module of the MAFM to identify the particular, unresponsive API(s).
- the API inspection module inspects APIs that that have been predetermined by the application developer to be critical to the operation of the microservice. The API inspection module then runs one or more sample input data requests through API gateway to test and pinpoint the immediate API source of the fault.
- a remedial action module of the MAFM is configured to determine an appropriate remedial action.
- the remedial action module inputs the identified, unresponsive API into a machine-learning model and determines a remedial action outcome.
- the remedial action includes terminating a container of the microservice associated with the unresponsive API and launching a new container of the microservice.
- the remedial action is rescaling a number of containers. Each container is associated with a microservice employing at least one API.
- the remedial action decision is communicated to a container platform interface module of the MAFM.
- the container platform interface interfaces with a container orchestration platform (e.g., KUBERNETES, DOCKER), which performs the actual remedial action by leveraging its native APIs.
- a monitoring scheduler module of the MAFM monitors a validity of the state of the API identified as unresponsive. The monitoring scheduler inputs test inputs to determine whether the once faulty API has been repaired by the remedial action.
- the monitoring process continues after a predetermined period of time.
- the monitoring process continues after a predetermined number of successful responses to API requests.
- the negative outcome is reported and stored in an API monitoring database as a source for historical outcome information.
- the historical outcome information whether indicating a successful or unsuccessful outcome, is fed to the machine learning algorithm of the remedial action module and assists in further refinements to the remedial action determination model.
- the availability of API endpoints in container orchestration platforms is improved within a microservices environment.
- the examples described herein of improving the availability of API endpoints in a microservices environment that employs a container orchestration platform are not meant to be limiting in any way. From this disclosure, those of ordinary skill in the art will be able to conceive many other ways of implementing the above enhancement. and the same are contemplated within the scope of the illustrative embodiments.

Abstract
Description
- The present invention relates generally to a method, system, and computer program product for troubleshooting an unresponsive microservice. More particularly, the present invention relates to a method, system, and computer program product for improving the availability of API endpoints in container orchestration platforms.
- A microservice architecture (MSA) is a variant of a service-oriented architecture (SOA) structural style and is one that arranges an application as a collection of loosely coupled services, commonly referred to as microservices due to their narrow scope in executing smaller tasks. It is common for MSA's to be adopted for cloud-native applications, and applications using lightweight container deployment. A consequence of following an MSA approach is that the individual microservices are independently deployable and can be individually scaled. In a monolithic approach, an application supporting a plurality of functions would have to be scaled in its entirety even if only one of these functions had a resource constraint. With microservices, only the microservice supporting the function with resource constraints would be scaled out.
- Because of the large number of services as compared to monolithic application implementations, decentralized continuous delivery and DevOps with holistic service monitoring are used to effectively develop, maintain, and operate such applications. In this regard, container orchestration platforms have been developed for managing complex applications comprised of multiple microservices working together through application programming interfaces (APIs) that are not dependent on a specific code language. While containers and microservices exist independently and serve different purposes, they are often used together. Containers are an enabling technology for microservices, which is why microservices are often delivered in one or more containers. Since containers are isolated environments, containers can be used to deploy microservices quickly, regardless of code language used to create each microservice. When implementing and managing containers and microservices, DevOps teams must actively work to prevent problematic code, such as errant application code and unresponsive APIs.
- Embodiments of the invention are defined by the claims below, not this summary. A high-level overview is provided here to provide an overview of the disclosure, and to introduce a selection of concepts that are further described below in the detailed-description section below. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in isolation to determine the scope of the claimed subject matter.
- The illustrative embodiments provide a method, system, and computer program product. An embodiment includes a method that invokes, using a service request handler module of a microservice application programming interface (API) fault manager (MAFM) a microservice API fault management service, responsive to detecting an unresponsive microservice managed by a container orchestration platform. An embodiment identifies an unresponsive API of the unresponsive microservice using an API inspection module of the MAFM. An embodiment determines, using a remedial action module of the MAFM, a remedial action to correct an unresponsive state of the unresponsive API. An embodiment communicates, using a container platform interface module of the MAFM, the remedial action to the container orchestration platform.
- An embodiment includes a computer usable program product. The computer usable program product includes one or more computer-readable storage devices, and program instructions stored on at least one of the one or more computer-readable storage devices.
- An embodiment includes a computer system. The computer system includes one or more processors, one or more computer-readable memories, and one or more computer-readable storage devices, and program instructions stored on at least one of the one or more computer-readable storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories.
- Certain novel features believed characteristic of the invention are set forth in the appended claims. The invention itself, however, as well as a preferred mode of use, further objectives and advantages thereof, will best be understood by reference to the following detailed description of the illustrative embodiments when read in conjunction with the accompanying drawings, wherein:
-
FIG. 1 depicts a block diagram of a network of data processing systems in which illustrative embodiments may be implemented; -
FIG. 2 depicts a block diagram of a data processing system in which illustrative embodiments may be implemented; -
FIG. 3 depicts a block diagram of a microservice API fault manager (MAFM) in which illustrative embodiments may be implemented; -
FIG. 4 depicts a block diagram of a microservice operating environment incorporating the MAFM and container orchestration platform in which illustrative embodiments may be implemented; -
FIG. 5 depicts a flowchart of a process for API fault detection and remediation in a microservice operating environment, in accordance with an illustrative embodiment. - The illustrative embodiments recognize that there is a need in a microservice operating environment that is managed by container orchestration platforms to ensure the validity of application programming interfaces (APIs), which are responsible for connecting the data and presentation layers of an application. Because the API layer directly touches both data and presentation layers, it is a key area for continuous testing for quality assurance (QA) and development teams. While there are many aspects of API testing, it generally consists of making requests to a single API endpoint or sometimes multiple API endpoints and validate the response, whether for performance, security, and/or functional correctness.
- The illustrative embodiments further recognize that container orchestration platforms, such as KUBERNETES and DOCKER, when implemented to manage complex application environments having a large number of microservices, generally only provide capabilities to monitor and scale pods (i.e., individual microservices) in the event that there is a failure within a container associated with a plurality of microservices. Current container orchestration platform technologies are not designed to validate and take any remedial action(s) based on problems related to the actual application logic and the APIs running within the failing container. As a result, current container orchestration platforms may simply remedy a failing container by replacing it with a newly spawned container, which is identical in the number and organization of microservices and their supporting APIs when compared to the contents of the failed container. In this regard, current container orchestration platforms may mistakenly treat the newly spawned container as a healed container, when in reality one or more of the supporting APIs are unresponsive and the API's failed state remains undetectable to current container orchestration platforms. This causes the application as a whole to become unresponsive.
- The illustrative embodiments also recognize that traditional third-party tools for monolithic applications, which provide fault tolerant and high availability solutions, are ineffective in microservice-based environments because of their inability to perform API validation and healing. Moreover, illustrative embodiments recognize that other solutions for monolithic environments, such as network devices and API gateways providing continuous API monitoring, carry the cost of performance degradation. Even other solutions designed for microservice-based environments fail to perform API validation and healing. Further, illustrative embodiments recognize that current microservice-based implementations employ application logics to perform checks on error codes and perform remedial actions based on the type of error code. However, even if a container orchestration platform terminates a pod and spawns another pod, such actions still do not guarantee individual API validation and healing.
- The illustrative embodiments recognize that the presently available solutions do not address these needs or provide adequate solutions for these needs. The illustrative embodiments used to describe the invention generally address and solve the above-described problems and other problems related to improving the availability of API endpoints under the management of container orchestration platforms in a microservice operating environment.
- An embodiment can be implemented as a software application. The application implementing an embodiment can be configured as a modification of an existing API gateway, a modification of an existing container orchestrator platform, as a separate application that operates in conjunction with an existing API gateway, as a separate application that operates in conjunction with an existing container orchestrator platform, a standalone application, or some combination thereof. Particularly, some illustrative embodiments provide a method that facilitates improving the availability of API endpoints under the management of container orchestration platforms in a microservice operating environment.
- An embodiment configures a microservice application programming interface fault manager (MAFM) to identify an unresponsive API and to determine a remedial action. According to one embodiment, the MAFM operations are triggered by a fault that is detected and communicated to a service request handler of the MAFM by third party monitoring tools, such as PROMETHEUS and GRAFANA. In other embodiments, the MAFM operations are triggered by a fault that is detected and communicated to the MAFM by an API gateway that is unable to gain a response from a requested API. In this regard, the fault detected by the API gateway appears to originate at a requested API, but it is not conclusive to be the actual source of the fault, as the requested API may itself depend upon other nested APIs.
- Another embodiment configures an API inspection module of the MAFM to identify the particular, unresponsive API(s). According to one embodiment, the API inspection module inspects APIs that that have been predetermined by the application developer to be critical to the operation of the microservice. The API inspection module then runs one or more sample input data requests through API gateway to test and pinpoint the immediate API source of the fault. According to another embodiment, after detecting the unresponsive API, a remedial action module of the MAFM is configured to determine an appropriate remedial action. According to one embodiment, the remedial action module inputs the identified, unresponsive API into a machine-learning model and determines a remedial action outcome. According to one embodiment, the remedial action includes terminating a container of the microservice associated with the unresponsive API and launching a new container of the microservice. According to another embodiment, the remedial action is rescaling a number of containers. Each container is associated with a microservice employing at least one API.
- According to one embodiment, the remedial action decision is communicated to a container platform interface module of the MAFM. The container platform interface, in turn, interfaces with a container orchestration platform (e.g., KUBERNETES, DOCKER), which performs the actual remedial action by leveraging its native APIs. According to another embodiment, a monitoring scheduler module of the MAFM monitors a validity of the state of the API identified as unresponsive. The monitoring scheduler inputs test inputs to determine whether the once faulty API has been repaired by the remedial action. According to another embodiment, the monitoring process continues after a predetermined period of time. According to another embodiment, the monitoring process continues after a predetermined number of successful responses to API requests. If any fault continues to be detected, the negative outcome is reported and stored in an API monitoring database as a source for historical outcome information. The historical outcome information, whether indicating a successful or unsuccessful outcome, is fed to the machine learning algorithm of the remedial action module and assists in further refinements to the remedial action determination model.
- In view of the foregoing embodiments, the availability of API endpoints in container orchestration platforms is improved within a microservices environment. The examples described herein of improving the availability of API endpoints in a microservices environment that employs a container orchestration platform are not meant to be limiting in any way. From this disclosure, those of ordinary skill in the art will be able to conceive many other ways of implementing the above enhancement. and the same are contemplated within the scope of the illustrative embodiments.
- The manner of repairing faulty APIs within a microservices environment that employs a container orchestration platform, as described herein, is unavailable in the presently available methods in the technological field of endeavor pertaining to API monitoring and fault remediation in microservice environments.

FIG. 3 , an example is shown of a microservice API fault manager (MAFM) 300 configured to identify an unresponsive API and to determine a remedial action, according to one embodiment of the invention. As shown, theMAFM 300 includes a servicerequest handler module 302, amonitoring scheduler module 304, anAPI inspection module 306, a containerplatform interface module 308, and aremedial action module 310. - According to an embodiment, service
request handler module 302 invokes, using a service request handler module of a microservice application programming interface (API) fault manager (MAFM), a microservice API fault management service. According to one embodiment, theMAFM 300 operations are triggered by a fault that is detected and communicated toservice request handler 302 of theMAFM 300 by third party monitoring tools (not shown), such as PROMETHEUS and GRAFANA. In other embodiments, theMAFM 300 operations are triggered by a fault that is detected and communicated to theMAFM 300 by an API gateway (404, shown inFIG. 4 ) that is unable to gain a response from a requested API. In this regard, each API request is transmitted via the API gateway and each API that is requested is associated with a particular address. In this regard, it is important to appreciate that although a fault detected by theAPI gateway 404 appears to originate at a requested API, such a detection is not necessarily conclusive that the requested API is the underlying source of the fault. According to one example embodiment, the requested API itself depends upon other API(s), whose unresponsiveness causes the requested API to also be unresponsive. - According to an embodiment,
API inspection module 306 inspects APIs that that have been predetermined by the application developer to be critical to the operation of the microservice. In one example embodiment, theAPI inspection module 306 runs one or more sample input data requests throughAPI gateway 404 to test and pinpoint the immediate API source of the fault. According to one embodiment, the sample input data requests are drawn from historical API requests that are previously stored in a database for machine learning and monitoring. - According to an embodiment,
remedial action module 310 of the MAFM is configured to determine an appropriate remedial action. According to one embodiment, theremedial action module 310 inputs the identified, unresponsive API into a machine-learning model and determines a remedial action outcome. The machine-learning model is updated based on historical data accumulated over the execution lifetime of the application. - According to an embodiment, container
platform interface module 308 serves as an interface with container orchestration platform (410 inFIG. 4 ). Container orchestration platform is responsible for executing the determined remedial action by leveraging its own native APIs. - According to an embodiment, a
monitoring scheduler module 304 monitors a validity state of the API identified as unresponsive. Themonitoring scheduler module 304 inputs test inputs to determine whether the once faulty API has indeed been repaired by the remedial action. - With reference to
FIG. 4 , a block diagram of amicroservice operating environment 400 incorporating theMAFM 300 and its interoperability withcontainer orchestration platform 410 andAPI gateway 404 is shown, according to one embodiment of the invention. In the example embodiment shown, three distinct application services: service A, B, C 403 a-c respectively send service requests throughAPI gateway 404. TheAPI gateway 404 handles these requests for particular APIs that are needed to successfully execute each discrete microservice that work together to execute the complex application. For example, application service A 402 a requiresmicroservice D 406 for successful execution. In particular, application service A 402 a requires access toAPI 1 408 a, which for purposes of this example is successfully accessed. However, continuing with the above example embodiment, application service B 402 b also requiresmicroservice D 406 and in particular requires access toAPI 2 408 b. In this example embodiment, however, application service B 402 b is unable to accessAPI 2 408 b and its microservice request times out. In this regard,API gateway 404 is responsible for handling the microservice request and is responsible for alertingMAFM 300 of the unresponsive event. In particular, the alert is communicated toservice request handler 302, which invokes the microservice API fault management service.Service request handler 302 initiatesAPI inspection module 306, which inspects APIs that that have been predetermined by the application developer to be critical to the operation of theunresponsive microservice D 406. In the example embodiment,API inspection module 306 identifies that bothAPI 2 408 b andAPI 3 408 c are unresponsive. - Once
API inspection module 306 has identified the API responsible for the microservice's failure,API inspection module 306 initiates the services ofremedial action module 310. In the example embodiment shown,remedial action module 310 is configured to determine an appropriate remedial action to heal the unresponsive state of theunresponsive API 2 408 b and API3 408 c. According to one embodiment, the remedial action module inputs the identified, unresponsive APIs 408 b-c into a machine-learning model and determines a remedial action outcome. According to the example embodiment, the remedial action includes terminating the container of theunresponsive microservice D 406 associated with the unresponsive APIs and launching a new container of the microservice, e.g.,new microservice D 412, having newly spawned APIs 1-3 414 a-c. - The remedial action decision is communicated to container
platform interface module 308. Containerplatform interface module 308 interfaces withcontainer orchestration platform 410, which performs the remedial action by leveraging its native APIs. However, it should be appreciated that the remedial action may not resolve the unresponsiveness of the microservice. For this reason, monitoringscheduler module 304 monitors a validity of the state of the new APIs that were previously identified inmicroservice D 406 as unresponsive.Monitoring scheduler module 304 invokes test cases as inputs to determine whether the oncefaulty APIs microservice D 412 and creatingAPIs API monitoring database 416 as a source for historical outcome information. The historical outcome information, whether indicating a successful or unsuccessful outcome, is supplied to the machine learning algorithm of theremedial action module 310 and assists in further refinements to the remedial action determination model. According to the example embodiment, having terminated the previous container ofmicroservice D 406 and spawning a workingmicroservice D 412, application service C 402 c is shown to requestmicroservice D 412 and in particular require access toAPI 3 414 c. In this example embodiment, application service C 402 c is able to accessAPI 3 414 c, whose now terminatedpredecessor API 3 408 c would have not been accessible. - With reference to
FIG. 5 , this figure depicts a flowchart of anexample process 500 for API fault detection and remediation in a microservice operating environment as described inFIG. 4 . The process begins atblock 502 and proceeds to block 504, where an application service is initiated (e.g., application service A-C 402 a-c), which includes the requesting of one or more microservices (e.g., microservice D 410) viaAPI gateway 404. Fromblock 504, the process continues to decision block 506, where it is determined byAPI gateway 404 whether the requested microservice is responsive to the request. If the microservice is responsive, the process terminates atblock 524. However, if it is determined that the requested microservice is unresponsive, the process continues to block 508, whereAPI gateway 404 alertsservice request handler 302, which invokes the microservice API fault management service. Fromblock 508, the process continues to block 510, whereAPI inspection module 306 identifies the unresponsive API(s). After identifying the unresponsive API(s), the process continues to block 512, whereremedial action module 310 determines a remedial action to correct the unresponsive state of the API(s) (e.g.,APIs platform interface module 308 communicates the remedial action (e.g., spawn new microservice/container D 412) tocontainer orchestration platform 410, which then executes the remedial action using its native APIs (block 516). Fromblock 516, the process continues to decision block 518, wheremonitoring scheduler module 304 verifies whether the remedial action has resulted in a valid state for the requested API (e.g., newly spawnedAPIs monitoring scheduler module 304 reports the positive outcome toAPI monitoring database 416. TheAPI monitoring database 416 stores the historical outcome data and is in communication withremedial action module 310, which accesses the outcome data to further refine the remedial action determination model. Fromblock 520, the process ends atblock 524. However, if an invalid state of the API is determined indecision block 518, the process continues to block 522, wheremonitoring scheduler module 304 reports the negative outcome toAPI monitoring database 416. TheAPI monitoring database 416 stores the historical outcome data and is in communication withremedial action module 310, which accesses the outcome data to further refine the remedial action determination model. Fromblock 522, the process loops back to block 510, whereAPI inspection module 306 seeks again to identify the source of the unresponsiveness. - Thus, a computer implemented method, system or apparatus, and computer program product are provided in the illustrative embodiments for improving the availability of API endpoints in container orchestration platforms. and other related features, functions, or operations.
